CLICK-SPRING FOR WATCHES.

SPECIFICATION forming part of Letters Patent No. 252,645, dated January 24, 182.

Application filed September 12, 1881.

To all whom itmay concern Be it known that I, ANTOINE LOUIS Grs- BERT BUYS, of Geneva, Switzerland, have invented a new and useful Improvement in WV-atches, of which the followingis a specification.

The annexed drawings represent the works of a watch provided with the piece R, which makes the object of the present claim for a patent, and which is reproduced separately in Figure 2 This piece R is a combined clickspring, which unites 1n asiugle piece the clickspring and the click usually used for the mechanism of keyless watches of every description. This click-spring ismade and combined in such a manner as to produce an easy and sure working of the click, and to obtain a long" springblade,\vhich preventsits breaking. This spring is secured in its right place by a single screw, and it is within a recess in the watch -plate (No model corresponding to the segmental end of the bridge B, around which such spring bears in consequence of its contractile properties, and the spring is expanded by the action of the teeth as they pass across its inclined end in winding the watch. This click-spring having a segmental bearing around which it contracts is supported thereby, and is not liable to be injured by the pressure againstthe end of the click.

I claim as my invention- The click and curved spring made in one piece,in combination with the segmental hearing around which the curved spring passes, substantially as specified.
